【ESC Functions】

►Restor factory defaults

ESC factory default state:

A Brake: OFF
B Battery type：Li-Po battery

C Low-voltage protection point: medium(3.0V/65%)
D Motor timing: autumatical
E Acceleration start：soft
F Helicopter mode：OFF
G Working frequency: 8kHz
H Low-voltage protection mode: decrease power

►Battery type (LiPo/NiMh/NiCd) setting
►Brake setting (with/without)
►Low-voltage protectionvaluesetting( low-voltage protection value:2.8V、3.0V、3.2V)
】►Acceleration start etting(specilized for RC helicopter)
►Helicopter mode(specilized for RC helicopter

A .Helicopter1:After startup,from 0% throttle advance to 100% after 5 seconds

B .Helicopter2:After startup,from 0% throttle advance to 100% after 10 seconds

Note: If helicopter mode, ESC default is no brake, default low-voltage protection type is power deduction.

►Motor rotation direction(clockwise/anticlockwise)
►Working frequency(8kHz/16kHz)
►Low-voltage protection mode(power reduction /stop immediately)

【Program ESC with transmitter】

Move throttle stick to the top ,then power up transmitter and ESC.ESC exits program mode at this time.Refer to the following chart, when the music that you need programming this option starts, move throttle stick to the bottom.Motor emits “BEEP-BEEP”at this time, it shows your selected option has programmed successfully. The prompt tone of each option plays 4 times, move the throttle stick to the bottom before finishing 4 times.Disconnect the power after finishing program then repower every time,it can run normally.

【Program with programming box】

Program： （5 types Prompt tone are as following ）
A=BEEP- short sound
B=BEEP-BEEP-BEEP- 3 continuous sound
C=～BEEP gradient sound+BEEP
D=BEEP↘ low sound
E=BEEP-- long sound
music 1 / throttle----throttle calibration / A-A-A-A
music 2 / brake / B-B-B-B
music 3 / Battery type / Ni-MH / C-C-C-C
music 4 / Li-Po / D-D-D-D
music 5 / Low-voltage protection threshold / low （2.8V） / E-E-E-E
music 6 / medium (3.0V) / AA-AA-AA-AA
music 7 / high (3.2V) / BB-BB-BB-BB
music 8 / Restore factory default / CC-CC-CC-CC

【Solutions to normal problems】

problems / Possible causes / solutions
After powering up,motor doesn’t run and doesn’t emit sound, servo system doesn’t connect,neither. / Bad connection between ESC and battery pack. / Clean the connectors or replace them,check the connection polarity.
Signal wire connects with wrong polarity of receiver / Check signal wire and make sure the right polarity.
Bad soldering cause bad contact. / Solder the wires again.
The wrong polarity connection between each battery. / Check battery pack, replace battery pack with on-specification ones.
Quality problem of ESC / Change ESC
After powering up,ESC emits the sound of battery cells automatic detection, but motor can’t start. / ESC doesn’t calibrate throttle / Do throttle calibration
After powering up ESC,ESC runs but motor can’t run and doesn’t emit sound. After powering up ESC,motor doesn’t run and emits warning tone(short stop after “BBE-BEEP”) / Bad connection between ESC and motor, or bad soldering . / Check the connectors or replace the connectors or solder the motor wire again.
Bad motor / Change motor
ESC low-voltage protection，battery voltage isn’t in the acceptable range / Check the voltage of battery pack and change the full-charged battery pack.
After powering up,motor doesn’t work and emits warning tone(“BEEP-BEEP”,short stop after first “BEEP” / No output throttle signal of receiver / Check if right connection between signal wire and receiver throttle channel.
Check transmitter and receiver,make sure signal output.
After powering up,motor doesn’t work and emits continuous warning tone / Throttle stick doesn’t put in the bottom. / Move the throttle stick to the bottom and calibrate throttle again.
After powering up,motor doesn’t work .ESC emits 2 long “BEEP”and 2 short “BEEP”. / The positive and negative of throttle channel was put wrong. So ESC exits program mode. / Refer to the user instruction of transmitter, adjust the setting of throttle channel.
Motor rotates in the anticlockwise direction / The wrong sequence of connection wires between motor and ESC. / ①Exchange random 2 of the 3 connection wires between ESC and motor.
②Change motor rotation direction with transimitter or programming box.
Motor stops running during flying / Battery voltage is lower than low-voltage protection threshold and low-voltage protection mode is cutoff output. / ①Set right low-voltage protection threshold. Fly with full-charged battery pack.Choose power reduction as Low-voltage protection .If power is decreasing during flying, please land your aircraft soon.
②Control your aircraft during the range available to control with your transmitter.
③Attention to the voltage of transmitter, if it wil run out of the battery,please land your aircraft soon.
Loss of throttle signal / ①Check if the right operation of the transmitter
②Check if the right match between transmitter and receiver.
③Strong electromagnetic interference in the used environment, try to repower up .
Start and restore the normal work, if the problem come up again and again, please change the flying field.
Bad contact of the connection wire / Check the connectors of battery pack, battery output wires and motor connection wires.

【Safety knowledge when using ESC】

●Please don’t remove the components on ESC, or it may cause permanent damage

●First time to test ESC and motor,if not sure the right setting of receiver,please don’t install propeller and pinion.

●Please don’t use broken,short-circuited and easy-heated battery pack.

●Please don’t use substandard cables and cords and connectors.

●Battery cells and servos number can’t be above ESC standard.

●Please mind battery polarity, wrong polarity connection will damage ESC.

●Please don’t put ESC in the moist and bright light place.
●Please don’t remove battery when motor is rotating, it will cause the huge peak current and burn ESC.

●Please install ESC in the ventilated place.

●Please don’t use with antimagnetized motor.

●Please don’t let ESC touch chemicals and water.

●If not use ESC in a period, please disconnect battery pack.
